OF SAID FRANK W. LIERMAN, DECEASED.

POWER-GENERATING- APPARATUS.

To all whom it may concern.

Be it known that I, FRANK W. L'IERMAN, a citizen of the United States, residing-at Milwaukee, in the county of Milwaukee and State of lVisconsim'have invented certain new and useful Improvements in ,Power- Generating Apparatus, of which the 'follow mg is aspecification.

A serious'objeotion to the combustion 01 fuel within the cylinder of a motor, as is done in the ordinary internahcombustion engine, is-that much ofthe heat generated is lost in the cooling water or other fluid required to keep the cylinder at a pro er work; r ing temperature. The burning o the fuel n the engine der, but in a separate furnace or combustion chamber, and the products of combustion are conducted to the motor, where the form Work-in expanding. Combustion is supported and the products of'combustion diluted to reduce them toga temperature suitable for use in the motor, by means of air supplied to the furnace by an air oompressor which may beoperated by the motor.

The accompanying drawing is a diagrammatic representation ofanapparatus embodying the features of my invention.

The generator 1 comprises an air-tight container which may be divided by a partition 2 into an air chamber 3 and a combustion and expansion chamber 4. The present embodiment, which is especially intended for use with hydrocarbon or other liquid fuel, comprises a spraying, nozzle 5 thatis mounted in the axial center of the combustion and expansion-chamber 4 at a little dis-K tance above the floor 6 thereof. Surrounding the spraying nozzle 5 is a basin 7 for confining the drippings or overflow of the fuel oil.

Combustion may be started by means of an electric igniter 21 arran ed to ignite the hydrocarbon in the basin or the-vapors rising from said hydrocarbon. 22 is a safety Before putting. the ap tion, the generator 1 is cient quantity of air to aratus in operalled with a sufli raised to the point where it can be utilized in the motor. When the valve 12 is opened, the fuel oil flows into the is ignited by meansof the electric igniter 21. The heat enerated and the-vaporizacauses the pressure of the eneratortorise to a pointapted. for use in the motor. The valve 16 isthen opened, admitting the pressure gases to the motor. The operation of the latter causes the air compressor 17 to be operated to deliver air to the air chamber 3. a

I aim'to obtain inthe generatorl practically perfect oxidation of the fuel, the pressure fluid passing to the motor being a mixture of 'carbondioxid, nitrogen and steam, but under certain working conditions are'latively small portion-of the oxygen of contents of the valve upon the generator'l.

The temperature in the fire hood 8 approximates the temperature of combustion, but the temperature of the products of combustion is reduced through dilution with atmospheric nitrogen and through expansion in the chambert prior to their passage to the motor.

Obviously the area of the compressor lunger or piston must be less than the area v of the engine piston.
